Its good to see that Joe's method is still being used by some, it works quite well, sometimes the retainers or collets may drop out while trying to release the spring but 2 cable ties sure beats a expensive tool...

Joe is going to be doing a video for youtube soon on a briggs valve job, as this morning I dropped off a 3.5hp sidevalve briggs with valve issues (no compression at all) that should make for an interesting vid on the findings.
